The aim of the present study was to establish the discriminating value of dermatoglyphic traits between schizophrenic patients and mentally healthy individuals.
The study included 76 schizophrenic inpatients (43 men, 33 women, mean age 31.47 years), who satisfied the DSM-IV criteria for a diagnosis of schizophrenia and 82 mentally healthy subjects of Bulgarian origin of mean age 39.24 years. Fingerprints were obtained by the ink method. Ridge count was read by the method of Cummins and Midlo.
The male schizophrenic patients showed a significantly higher total finger ridge count of each hand and TFRC than the control group. On the right hand, statistically significant differences were found for D2 and D5. On the left hand, the differences reached statistical significance for L1, L2 and L5. The schizophrenic females had lower ridge count than the control group females. The differences were most expressed for the total ridge count of the left hand (TFRCL) and total ridge count of both hands (TFRC), but did not reach statistical significance. On the right hand the greatest between-group differences were found for D1 and D4, which were just short of reaching statistical significance (p > 0.05). On the left hand the greatest differences (almost reaching statistical significance) were found for L1. Of the other fingers the greatest differences showed L3 and L4.
Total finger ridge count appears to be a sensitive trait indicating disorders of prenatal neurodevelopment in schizophrenia.
本研究旨在确定精神分裂症患者与心理健康个体之间皮纹特征的鉴别价值。
该研究纳入了76例精神分裂症住院患者（43名男性，33名女性，平均年龄31.47岁），他们符合精神分裂症诊断的DSM-IV标准，以及82名保加利亚裔心理健康受试者，平均年龄39.24岁。采用油墨法获取指纹。嵴纹计数采用卡明斯和米德洛方法读取。
男性精神分裂症患者每只手的总指嵴数和总指嵴纹数均显著高于对照组。右手方面，D2和D5存在统计学显著差异。左手方面，L1、L2和L5的差异具有统计学意义。精神分裂症女性的嵴纹数低于对照组女性。差异在左手总嵴纹数（TFRCL）和双手总嵴纹数（TFRC）方面最为明显，但未达到统计学意义。右手方面，D1和D4的组间差异最大，几乎达到统计学意义（p>0.05）。左手方面，L1的差异最大（几乎达到统计学意义）。在其他手指中，L3和L4的差异最大。
总指嵴纹数似乎是一个敏感特征，表明精神分裂症患者存在产前神经发育障碍。
